T 2.3.9.29

But this principle of the connexion of fear with uncertainty I carry farther, and observe that any doubt produces that passion, even tho' it presents nothing to us on any side but what is good and desireable. A virgin,virgin on her bridal-night goes to bed full of fears and apprehensions, tho' she expects nothing but pleasure of the highest kind, and what she has long wish'd for. The newness and greatness of the event, the confusion of wishes and joys, so embarrass the mind, that it knows not on what passion to fix itself; from whence arises a fluttering or unsettledness of the spirits, which being, in some degree, uneasy, very naturally degenerates into fear.
